Sanitation and Human Health


Content Source:

Science NetLinks
Type: Lesson/Unit Plan


In this lesson, students will develop an understanding of the impact of improved sanitation on human health. They do this by examining the history of sanitation in the context of disease outbreaks and comparing the quality of life in earlier times to that of today. Students should recognize that advances in health and human life expectancy have resulted in large part because of technologies that we now take for granted, such as modern waste disposal, sanitary food handling, and refrigeration.

Content Standard(s):
SC2015 (2015)
Grade: 7
Life Science
9 ) Engage in argument to defend the effectiveness of a design solution that maintains biodiversity and ecosystem services (e.g., using scientific, economic, and social considerations regarding purifying water, recycling nutrients, preventing soil erosion).

Unpacked Content
Scientific And Engineering Practices:
Engaging in Argument from Evidence
Crosscutting Concepts: Stability and Change
Disciplinary Core Idea: Ecosystems: Interactions, Energy, and Dynamics
Evidence Of Student Attainment:
  • Argue using evidence to support claims of the effectiveness of the design solution.
Teacher Vocabulary:
  • Evidence
  • Engineering design process
  • Design solution
  • Biodiversity
  • Ecosystem
  • Ecosystem service
  • Scientific argument
  • Criteria
  • Constraint
  • Economic considerations
  • Social considerations
  • Recycling nutrients
  • Soil Erosion
  • Water Purification
Students know:
  • Evidence about performance of the given design solution. Biodiversity describes the variety of species found in the earth's ecosystems.
  • The completeness of the biodiversity of an ecosystem is often used as a measure of health.
  • Changes in biodiversity can influence humans' resources and ecosystem services.
Students are able to:
  • Identify and describe a given design solution for maintaining biodiversity and ecosystem services.
  • Identify and describe the additional evidence (in the form of data, information, or other appropriate forms) that is relevant to the problem, design solution, and evaluation of the solution.
  • Collaboratively define and describe criteria and constraints for the evaluation of the design solution.
  • Use scientific evidence to evaluate and critique a design solution.
  • Present oral or written arguments to support or refute the given design solution.
Students understand that:
  • There are processes for evaluating solutions with respect to how well they meet the criteria and constraints.
